  • Occupancy (Auto On, Auto Off): Select this option if you want the fan to turn off when no motion is detected and turn on when motion is detected again.
  • Vacancy (Manual On, Auto Off): Select this option if you want the fan to turn off when no motion is detected and remain off when motion is detected again. The fan must be turned back on manually each time it is turned off by the occupancy sensor.

  • Unoccupied Behavior: Specify what the fan should do when no motion is detected: turn off or mix warm air near the ceiling with cooler air near the floor at a low speed.

Trouble with Something Else

A popping noise is coming from my fan.

Airfoil noise occurs when airfoils are not tightened to the specified torque. Disconnect the fan from power, and then tighten the airfoil hardware to 29 ft·lb (39.3 N·m). Note: If the hardware is stainless steel, tighten the airfoil hardware to 10 ft·lb (13.6 N·m). If popping still occurs, verify that the airfoils are not contacting each other. If they are, contact Customer Service.

My fan wobbles during operation.
  • Verify that the mounting structure is rigid enough to support the fan and that the fan is not being exposed to external air forces.
  • If guy wires were installed, confirm proper installation. If guy wires were not installed, contact Customer Service.
My fan’s VFD generates radio frequency (RF) noise.

VFDs generate RF noise in many ways, but this can be prevented using proper wiring practices.

  • Do not run your fan and sensitive equipment on the same power line.
  • Ensure proper grounding at the motor, at the VFD, and from the VFD to the utility.

If noise is still present, contact Customer Service.

My fan’s motor makes noise when the speed is increased.
  • Audible high-frequency carrier noise may be an indicator of a stall condition.
  • Some motor, gearbox, or VFD noise is to be expected and is normal.
